RUFUS SIBLEY, OF GREENVILLE, CONNECTICUT, ASSIGNOR TO SAMUEL MOVRY, OF SAME PLACE.

PRESS FOR PHOTOGRAPHS.

Specification forming part of Letters Patent No. 35,570, dated .lune 10,186?.

To all whom it may concern.-

Be it known that I, RUFUS SIBLEY, of Greenville, in the county ot' New London and State of Connecticut, have invented certain new and useful Improvements in Photograph-Presses; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference being` had to the accompanying drawings, making a part of this specification, in which- Figure l represents a perspective view of the press. Fig. 2 represents a vertical cross section through the same.

The object and purpose of my invention is to make a cheap, etiicient, and powerful press for pressing photographic pictures` which shall not be bulky or unwieldy. This I have accomplished, as I will hereinafter explain.

My invention consists in the use, in connection with a suitable bed, of a polishing-roll set and turning in a traveling truck or carriage,-

and guided and controlled by ways and setscrews to regulate the necessary pressure between the roll and bed, for the purposes hereinatter specitied.

To enable others skilled in the art to make Aand use my invention, I will proceed to describe the same with reference to the drawings.

The bed A and columns B may be cast in one piece. That portion of the bed marked C is raised higher than the other parts, so that it alone may be planed oft' without planing otf the other portions. The tops of the columns B may be planed off at the same time that the portion C is, which will insure their parallelism, as they bear particular working relations to each other.

D D are two side rails, their upper edge or side arched for the sake of` strength, and the under side planed to make a true way for the truck-wheels to run against. These rails are snugly fitted to the tops of the columns, and by means of screws or otherwise may be made adjustable thereon.

E is a east-iron frame made with suitable recesses and boxes for the journals a of the truck-wheels b to turn in, as also for the wheels themselves to revolve in. The wheels Z1 are of cast-iron, and may be cast onto the axles or journals, which are of wroughtdron. They have flanges c upon them, that bear against the inside of the rails D to keep the truck or carriage from moving` laterally.

Pillar-blocks c are cast on the under side ot the frame E, for supporting properly the boxes ff for the journals /t of the polishingroll F. and set-screws l(/ r/ pass through the frame E and against the boxes or followers f, for rcgulating the pressure of the polishing-roll upon the picture.

The truck or carriage can be easily removed from the bed and rails for cleansing itor for repair by simply running up the set-screws.

G is a crank arranged upon the protruding journal 71 of the polishing'roll for turning said roll. In ordinary eases this crank will be found to be sufiicient to turn the roll with when the pressure is upon it; but should it not be powerful enough, the crank may be connected to a spur-wheel, which may work with a gear-wheel ou the journal ot the roll, and thus increase the facility for revolving the polishingroll.

In operating this press a steel plate, with its polished side up, is laid upon the bed C.

The picture to be polished is -laid upon this polished plate with the face down, and the finishing-roll (which may also be ot' polished steel) is run over-the picture once or twice, which completes the process. The friction or traction between the truck -whcels and the rails and between the polishing-roll and the bed or picture causes the truck or carriage to move along over the picture with great regularity, while the pressure can be regulated at any time on one or both ends of the roll, as may be required. 1

Having thus fully described the nature and objects of my invention in photograph-presses, what I claim therein as new, and desire to secure by Letters Patent, is

In combination with the bed and rails, the traveling truck or carriage, and the polishingroll operating iu connection therewith, sub stantially in the manner and for the purpose herein described.

RUFUS SIBLDY.
